Porting Process of number portability
Subscriber Sends the request for Porting to 1900 in the format
PORT<space>10 digit mobile Number
(All operators will route 1900 to their respective Number Portability
Gateways(NPG))
 The NPG will Generate a Unique Porting Code (UPC) 8 Character Code
with first character indicating Donor Operator and Second Character the
LSA eg AX12E531- Airtel Karnataka
 The Subscriber approaches Recipient Operator(RNO) fills the CAF which
now has the UPC Filed
 The RNO through CCN raises the Porting request after allotting a SIM to
the Subscriber (SIM Number has to be filled in while raising the request)
 The request reaches MCHA(MNP Clearing House Administrator) through
NPG
(The RNO has the access to GUI of NPG and MCHA for tracking the request)

MCHA sends a request to donor Operator (DNO) for approval of
the NP request
DNO approves the Porting (if the subcriber was active in the
DNO for at least 90 days, No Pending invoice, and no legal/vigilance
cases) , after intimating Law Enforcement Agency (LEA) if the
number is under Lawful Interception(LI) . (Must Have a nodal
Officer for this)
The MCHA schedules the porting Process and intimates both
DNO and RNO of the date and time of porting. The billing system
carries out the requests automatically.
After Porting the Change of LRN (Location Routing Number) is
broadcasted by the MCHA through NPG to all the L-NPDB. (Local
